Definition

Intubation and mechanical ventilation is the use of a tube and a machine to help get air into and out of your lungs. This is often done in emergencies, but it can also be done when you are having surgery.

Endotracheal Intubation

Reasons for Procedure

Your lungs help exchange gases in your body. Oxygen is moved from the air in your lungs into your blood, and carbon dioxide in your blood moves into the air in your lungs. This movement of gases is needed to live. If you cannot move air into and out of your lungs, then this gas exchange cannot happen. Intubation and mechanical ventilation is done to help you breathe when you cannot move enough air in and out on your own.

Possible Complications

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

Damage to teeth, lips, or tongue

Damage to the trachea or larynx resulting in pain, hoarseness, or difficulty breathing after the tube is removed

Esophageal intubation—when the tube is accidentally inserted into the esophagus and stomach rather than the trachea

What to Expect

Prior to Procedure

If your intubation and mechanical ventilation is being performed along with surgery and is planned:

The night before, eat a light meal. Do not eat or drink anything after midnight.

Ask your doctor about any other special directions.

Anesthesia

In most cases, you will either be heavily sedated or under
general anesthesia
and asleep. Local anesthesia may be used to numb your throat. You may also receive a muscle relaxant. This is to prevent gagging when the tube is inserted.

Description of the Procedure

First, you will wear an oxygen mask for 2-3 minutes. This will ensure that you have enough oxygen in your system during the procedure.

Your head will be tilted back slightly. A tool called a laryngoscope will be used. The scope has a handle, a light, and a smooth dull blade. This tool lifts the tongue off the back of the throat so your vocal cords can be seen. One end of the breathing tube will be inserted through the vocal cords and into your lower windpipe.

When the tube is in position, the scope will be removed and the tube will be left in place. Next, the tube will be attached to a ventilator machine. The tube will then be taped to the corner of your mouth. This machine will move air in and out of your lungs. It can adjust how quickly and how deeply you breathe. In some cases, the tube will be inserted through the nose instead of the mouth.

Immediately After Procedure

Right after the procedure, your doctor will:

Listen to your lungs to make sure that the air is going into them equally

Do a
chest x-ray
to make sure the tip of the tube is positioned in the middle of your trachea

Measure the level of gases in your blood to make sure that the ventilation is working

How Long Will It Take?

Less than 5 minutes

How Much Will It Hurt?

The anesthesia will prevent pain during the procedure. The tube will cause discomfort and may make you cough.

Average Hospital Stay

This procedure is done in a hospital setting. The usual length of stay depends on why you are having the procedure.

Post-procedure Care

While you are intubated, you will receive extra help from nurses and other hospital staff.

You will not be able to eat, drink, or talk until the tube is removed. Before the tube can be removed, you will need to:

Be effectively breathing on your own through the tube, without the ventilator attached. You may only be partially awake during this time.

Have made progress in:

How often you take a breath

How well oxygen is getting into your blood

How much air you breathe in and out each time you take a breath

If you need mechanical ventilation for more than a few weeks, a tracheotomy may be done. In this case, the airway tube is inserted through a hole made in your neck instead of your mouth or nose.
